The original title is about Cloud KMS and BYOK, discussing what you're actually trusting. Let me rewrite this for a mobile feed.

Short summary

Cloud key management security depends on where keys live and who controls access, not just where they originated. CMK and imported BYOK store keys in the provider's HSM under their access control; only external key managers (HYOK) give you unilateral revocation by keeping keys outside the provider entirely, at the cost of latency and availability.

• •Customer-managed keys (CMK) and bring-your-own-key (BYOK) both live in the provider's HSM and require provider cooperation to enforce revocation
• •Key origin (BYOK) differs from key custody—imported BYOK keys still live in provider infrastructure subject to their access policies
• •Only hold-your-own-key (HYOK) provides unilateral control: keys stay in your HSM, all crypto requests proxied in real-time, making provider access revocation immediate
